Digital services are services supplied over the internet or electronically. These attract different GST rules than physical goods. ATO treats digital services as place-of-supply services, meaning the location of the customer determines where GST is due.
OSS allows non-EU and Australian businesses to register for GST in a single EU member state and declare all B2C sales to customers across the EU in one return.
Register in an EU member state (usually where your business is based or where you want to declare sales). You'll receive an OSS registration and declare sales using the GST rate of the customer's country.
GST Rate Applied
Customer's country rate (0%-27%)
Place of Supply
Where the customer is established
Evidence Needed
IP address, billing address, payment method, SIM registration
Example
Selling a software licence to a German consumer requires German VAT (19% MwSt)
GST Rate Applied
Supplier's country rate (usually 10% in Australia)
Place of Supply
Where the supplier is established
Evidence Needed
Valid ABN, business documentation
Example
Selling SaaS to an Australian company with ABN = 10% GST applies
Key Difference: B2B sales follow the supplier's country rules; B2C follows the customer's country rules. Always verify the customer's GST status and location.

Proper record-keeping is essential for digital service GST compliance. You must maintain evidence of the customer's location and the GST rate applied.
Retention Period: Keep all records for at least 6 years. ATO may request documentation during audits to verify GST calculations and customer locations.
Are you GST-registered in Australia? Do you sell to overseas consumers (B2C) or businesses (B2B)? This determines whether GST applies and whether you need to register under standard or simplified GST for non-residents.
Register in an EU member state through your chosen tax authority. You'll provide business information and select your reporting member state.
Implement systems to capture and verify customer location (IP address, billing address, payment method). Configure your invoicing software accordingly.
Lodge your BAS quarterly through the ATO Business Portal or your tax agent's software. Report GST collected (1A), GST credits (1B) and net amount owing or refundable.
Pay the net GST amount owing on your BAS by the due date. Use BPAY, direct debit, or pay via the ATO portal. Keep records of all BAS lodgements and ATO correspondence.
MOSS (Mini One-Stop Shop) was replaced by OSS. MOSS is no longer available as of 2021. All businesses now use the standard OSS scheme for B2C sales.
Apply the hierarchy: billing address > IP address > payment method. If multiple sources conflict, document your decision and the evidence used. This is important for audit purposes.
If you can't determine customer location despite reasonable efforts, you may apply your own country's GST rate (10% in Australia). Document your evidence-gathering attempt.
OSS returns are filed electronically through your designated EU tax authority's portal. Most returns require CSV uploads of sales data by country. Filing is typically quarterly.
Australia-only sales follow standard Australian GST rules (10% standard rate). No OSS registration needed. File regular BAS (Business Activity Statement) with ATO using Single Touch Payroll.
